BACKGROUND

Mobile computing devices may use a wide variety of input methods. In addition to buttons and other physical input devices, mobile computing devices typically include an electronic display capable of detecting the presence and location of the touch within the display area (i.e., a “touchscreen”). Numerous software applications for mobile computing devices make use of touchscreen inputs, and thus touchscreens have dramatically expanded the type and range of possible user interactions with mobile computing devices.

However, touchscreen interactions require the user's focused attention to see a target to touch (e.g., an icon, text, etc.) or a response to the input. Further, more complex software applications or features may be difficult or cumbersome to control through interactions with a touchscreen. Moreover, many interactions with mobile computing devices have limited access to the touchscreen or require one hand to hold the mobile computing device so that fingers of the other hand may interact with the touchscreen.

SUMMARY

In some embodiments, detecting a trigger for a multisensor input mode may include detecting a third input from the second touch sensor.

In some embodiments, detecting a trigger for a multisensor input mode may include executing an instruction of an application configured to trigger entering the multisensor input mode.

Some embodiments may further include determining a multisensor input data structure associated with the trigger, and loading the multisensor input data structure.

Some embodiments may further include receiving the second input from the second touch sensor, identifying a first type of user interaction with the second touch sensor from the second input, identifying a first sensor input data in the multisensor input data structure corresponding with the first type of user interaction, identifying a multisensor input in an entry in the multisensor input data structure having the first sensor input data related to a multisensor input response.

In some embodiments, identifying a multisensor input in an entry in the multisensor input data structure having the first sensor input data related to a multisensor input response may include identifying the multisensor input in the entry in the multisensor input data structure having the first sensor input data and a device parameter data related to the multisensor input response.

DETAILED DESCRIPTION

The various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the invention or the claims.

The term “mobile computing device” is used herein to refer to any one or all of variety of small computing devices, particularly computing devices including touch sensors (e.g., capacitive sensors, pressure touch sensors, touchscreen displays, and other suitable sensors configured detect and localize a user touch on a surface of the device), a programmable processor and memory and circuitry for receiving user inputs. Examples of computing devices for which the various embodiments are particularly useful include smartphones, tablet computing devices configured to be held on the edges by a user, wearable computing devices, other similar computing platforms, and other similar devices.

The term “multisensor input” is used herein to refer to information received from at least one touch sensor on the mobile computing device distinct from a touchscreen of the mobile computing device. The multisensor input may reflect characteristics of various types of input detected by the at least one touch sensor including a duration of contact, a number of contact points, a size of the contact point(s), a sequence or contiguous series of contacts, a pattern of simultaneous contacts, and/or a level of pressure or force applied during the contact.

The term “operational context” is used herein to refer to the external environment that influences operation of an application on a mobile computing device. The hardware and software environment of the mobile computing device defines the operational context.

The term “data” is used herein to refer interchangeably to a singular datum and/or to a plurality of data. Examples of such use of the term “data” include, but are not limited to, the terms “data”, “sensor input data”, “device parameter data”, “location data”, “global positioning system (GPS) data”, “wireless connection data”, “peripheral device connection data”, “mobile computing device state data”, “application data”, “action data”, “contextual awareness data”, and “sensor data”.

Mobile computing devices are often configured with a touchscreen that serves as a display for one or more active applications, while also providing users an interactive input surface. Touchscreen technology enables users to accomplish many tasks on his or her mobile computing device, such as a smartphone, with ease and convenience by interacting with applications by touching the display on the touchscreen. Consumer demands for increased usefulness of mobile computing devices seems to compete with the small size of these devices and user desires to easily operate the devices with just a few fingers or even using only one hand. Touchscreen interactions require a user's focused attention to see a target to touch (e.g., an icon, text, etc.) or a response to the input. Further, more complex software applications may be difficult or cumbersome to control through interactions with a touchscreen. Moreover, many interactions with mobile computing devices require one hand to hold the mobile computing device so that fingers of the other hand may interact with the touchscreen. To address these issues, various embodiments provide additional touch sensors on the mobile computing device distinct from the touchscreen thereof.

Various embodiments include mobile computing devices having touch sensitive input sensors on multiple surfaces, such as rear or back, side(s), top, and bottom surfaces, and methods for interpreting touches on such surfaces to provide additional user input functionality.

Various embodiments enable a wide range of functionality and operational control of a mobile computing device that includes a plurality of touch sensitive input sensors on surfaces in addition to a touchscreen display, such as touch sensors positioned on the back area, the sides, the top edge, and the bottom edge of the device. By correlating detected touches and or gestures on two or more of the mobile computing device touch sensitive input sensors as well as an executing application and/or an operating state or condition of the device, various embodiments enable greater functionality and a broader range of user input controls that may be implemented with various applications.

Various embodiments may be implemented using a rules-based system that coordinates how inputs received from one or more touch sensors on the mobile computing device, distinct from or in addition to a touchscreen thereof, control and/or interact with applications running on the mobile computing device. For example, the received inputs from one or more touch sensors may be mapped to and interact with applications active with elements thereof displayed on the touchscreen. For example, received inputs from touch sensors disposed on the back and/or sides of the mobile computing device may control how content in the display on the touchscreen is represented and/or manipulated. In addition or alternatively, the received inputs from one or more touch sensors may control a background application distinct from an active application that dominates and/or controls the display on the touchscreen.

In various embodiments, a processor of the mobile computing device may disambiguate a user's intentions when a plurality of touch sensor readings are received as input. For example, when a user grips the mobile communication device with one or two hands and/or additionally contacts separate portions of the mobile communication device with one or more fingers, the processor may determine the grip contact may be ignored, but the finger contact may be acted upon.

In various embodiments, a processor of a mobile computing device including a plurality of touch sensors may monitor touch sensor measurements and generate a touch profile based thereon. As an example, the processor of the mobile computing device may generate a touch profile based on input from one or more touch sensors, other than or in addition to the touchscreen. The generated touch profile may reflect characteristics of various types of inputs including a duration of contact, a number of contact points, a size of the contact point(s), a sequence or contiguous series of contacts, a pattern of simultaneous contacts, and a level of pressure or force applied during the contact. In addition, the generated touch profile may reflect which received inputs may be ignored (e.g., normal grip patterns) and/or which may be acted upon (e.g., intentional touches). The processor may also use contextual awareness data in order to determine an operational context of the mobile computing device, which may dictate how or what to do with the generated touch profile. The contextual awareness data may reflect the settings/parameters from and state information of active applications and/or resources of the mobile computing device. In this way, the operational context of the mobile computing device may be used to determine what operations to perform based on the generated touch profile.

The computing devices and methods of various embodiments address a problem of deciphering intentions of a user of a mobile computing device in response to activation of multiple touch sensors of the mobile computing device. The various embodiments enable mobile computing devices configured with multiple touch sensors to distinguish between true and false inputs to the multiple touch sensors by processing signals from the multiple touch sensors.

Various embodiments may be implemented within a variety of mobile computing devices, an example of which is illustrated in FIGS. 1A and 1B. With reference to FIGS. 1A and 1B, a mobile computing device 100 may include a body 110 having a front area 112, a rear area 114, two sides 116 a, 116 b between the front area 112 and the rear area 114, and a top area 118 between the front area 112 and the rear area 114. The front area 112 may include a touch sensor 102 that may be incorporated within a display in the form of a touchscreen display. The rear area 114 may include a touch sensor 104. One or both of the sides 116 a, 116 b may include a touch sensor 106. The top area 118 may include a touch sensor 108. Thus, the body 110 of the mobile computing device 100 may include one or more touch sensors on the front area 112, the rear area 114, the one or more sides 116 a, 116 b, and the top area 118. The touch sensors 102, 104, 106, 108 may be configured to receive an input 124, 132 from a user's finger 120, 128 and/or an input 126, 134 from a user's thumb 122, 130.

A touch sensor 102, 104, 106, 108 is configured to detect a change in touch sensor state, such as a measurement of capacitance or pressure, at a location where the sensor is touched (or nearly touched) by an object, particularly by a user's hand, thumb, or fingers. While finger and thumb touch inputs 124, 126, 132, 134 on the touch sensors 102, 104, 106, 108 are illustrated in FIGS. 1A and 1B, the touch sensors 102, 104, 106, 108 may detect a change in touch sensor state from any contact with a user's body, such as contact with a user's palm or face, touches by a stylus or another similar input device, and the like. In some embodiments, a touch sensor 102, 104, 106, 108 may detect two or more contact locations (e.g., a multi-touch sensor). In some embodiments, a touch sensor 102, 104, 106, 108 may detect a pressure of one or more contacts. Outputs from the various touch sensors 102, 104, 106,108 may be provided to a processor (e.g., a processor that is included within or coupled to the touch sensors 102, 104, 106, 108) that is configured to determine locations of touches that may be treated as user inputs to the mobile computing device 100.

In some embodiments, a processor of the mobile computing device 100 and/or of the touch sensors 102, 104, 106, 108 may determine that one or more contacts have a duration that is less than, equal to, or greater than a threshold period of time. In some embodiments, such a processor may determine characteristics of the contact or contacts on one or more of the touch sensors 102, 104, 106, 108. For example, the contact characteristics may include a duration of contact, a number of contact points, a size of the contact point(s), a sequence or contiguous series of contacts, a pattern of simultaneous contacts, and a level of pressure or force applied during the contact(s). Contact associated with a user gripping the mobile communication device may be determined from various inputs, including a combination of concurrent contacts at multiple locations of the touch sensors 102, 104, 106, 108, which may be persistent for at least a minimum duration. In some embodiments, the processor of the mobile computing device may distinguish between a tap, a double tap, a long press, a sweep or flick, a drag, a predefined gesture including a plurality of touch and/or pressure inputs, a grip, other contacts, or any combination thereof. A predefined gesture may be a set or sequence of one or more contacts with the touch sensors 102, 104, 106, 108. The predefined gesture may be configured by a user, established by an application on the mobile computing device, or may be provided as a factory-installed default. In some embodiments, the touch sensors 102, 104, 106, 108 may be configured to detect a proximity or near-contact (e.g., a “hover”) by a user's finger or thumb prior to or without physical contact.

While touch sensors 102, 104, 106, 108 are discussed herein generally in terms of touch sensors that detect touches based on changes in capacitance, such sensors are used merely as an example of one type of input sensor suitable for use with the various embodiments. Other types of input sensors, such as resistive-sensing input sensors, infrared sensing input sensors, resistive force sensors, etc., may be used in various embodiments.

FIG. 2 is a functional block diagram of an example mobile computing device 200 that is suitable for implementing various embodiments. With reference to FIGS. 1A-2 , the mobile computing device 200 may be similar to the mobile computing device 100. For example, the mobile computing device 200 may be a multi-SIM computing device, such as a multiple SIM multiple standby (MSMS) computing device. The mobile computing device 200 may include at least one subscriber identity module (SIM) interface 202, which may receive a first SIM (“SIM-1”) 204 a that is associated with a first subscription. In some embodiments, the at least one SIM interface 202 may be implemented as multiple SIM interfaces 202, which may receive at least a second that is associated with at least a second subscription.

A SIM in various embodiments may be a Universal Integrated Circuit Card (UICC) that is configured with SIM and/or universal SIM (USIM) applications, enabling access to a variety of different networks. The UICC may also provide storage for a phone book and other applications. Alternatively, in a code division multiple access (CDMA) network, a SIM may be a UICC removable user identity module (R-UIM) or a CDMA subscriber identity module (CSIM) on a card.

Each SIM 204 a may have a CPU, ROM, RAM, EEPROM and I/O circuits. One or more of the first SIM 204 a and any additional SIMs used in various embodiments may contain user account information, an international mobile station identifier (IMSI), a set of SIM application toolkit (SAT) commands and storage space for phone book contacts. One or more of the first SIM 204 a and any additional SIMs may further store home identifiers (e.g., a System Identification Number (SID)/Network Identification Number (NID) pair, a Home PLMN (HPLMN) code, etc.) to indicate the SIM network operator provider. An Integrated Circuit Card Identity (ICCID) SIM serial number may be printed on one or more SIM 204 a for identification. In some embodiments, additional SIMs may be provided for use on the mobile computing device 200 through a virtual SIM (VSIM) application (not shown). For example, the VSIM application may implement remote SIMs on the mobile computing device 200 by provisioning corresponding SIM profiles.

The mobile computing device 200 may include at least one controller, such as a general-purpose processor 206, which may be coupled to a coder/decoder (CODEC) 208. The CODEC 208 may in turn be coupled to a speaker 210 and a microphone 212. The general-purpose processor 206 may also be coupled to at least one memory 214. The memory 214 may be a non-transitory tangible computer readable storage medium that stores processor-executable instructions. For example, the instructions may include routing communication data relating to a subscription though the transmit chain and receive chain of a corresponding baseband-RF resource chain. The memory 214 may store operating system (OS), as well as user application software and executable instructions. The general-purpose processor 206 and memory 214 may each be coupled to at least one baseband modem processor 216. Each SIM 204 a in the mobile computing device 200 may be associated with a baseband-RF resource chain that includes at least one baseband modem processor 216 and at least one radio frequency (RF) resource 218.

The RF resource 218 may include receiver and transmitter circuitry coupled to at least one antenna 220, and configured to perform transmit/receive functions for the wireless services associated with each SIM 204 a of the mobile computing device 200. The RF resource 218 may implement separate transmit and receive functionalities, or may include a transceiver that combines transmitter and receiver functions. The RF resource 218 may be configured to support multiple radio access technologies/wireless networks that operate according to different wireless communication protocols. The RF resource 218 may include or provide connections to different sets of amplifiers, digital to analog converters, analog to digital converters, filters, voltage controlled oscillators, etc. Multiple antennas 220 and/or receive blocks may be coupled to the RF resource 218 to facilitate multimode communication with various combinations of antenna and receiver/transmitter frequencies and protocols (e.g., LTE, WiFi, Bluetooth and/or the like).

The baseband modem processor 216 of a mobile computing device 200 may be configured to execute software including at least one modem stack associated with at least one SIM. SIMs and associated modem stacks may be configured to support a variety of communication services that fulfill different user requirements. Further, a particular SIM may be provisioned with information to execute different signaling procedures for accessing a domain of the core network associated with these services and for handling data thereof.

In some embodiments, the general-purpose processor 206, memory 214, baseband modem processor 216, and RF resource 218 may be included in a system-on-chip device 222. The SIMs 204 a and their corresponding interface(s) 202 may be external to the system-on-chip device 222. Further, various input and output devices may be coupled to components of the system-on-chip device 222, such as interfaces or controllers. Example user input components suitable for use in the mobile computing device 200 may include, but are not limited to, a keypad 224, a touchscreen 226, such as a beveled edge touchscreen, and one or more touch sensors 227. The one or more touch sensors 227 may be similar to the touch sensors 102, 104, 106, 108 described with reference to FIGS. 1A and 1B.

In various embodiments, the one or more touch sensors 227 may be connected to one or more microcontrollers 228, and the microcontroller(s) 228 may be connected to the general-purpose processor 206. In various embodiments, the microcontroller(s) 228 may be configured with microcontroller-executable instructions to perform operations to determine whether a contact is occurring on the one or more touch sensors 227. In various embodiments, the microcontroller(s) 228 may be configured with microcontroller-executable instructions to perform operations to determine the location of the contact. In various embodiments, the microcontroller(s) 228 may be configured with microcontroller-executable instructions to perform operations to send an indication of the contact including contact parameter information to the general-purpose processor 206. In various embodiments, the general-purpose processor 206 may receive an indication of a contact from the microcontroller(s) 228.

FIG. 3 illustrates a method of managing multisensor inputs according to various embodiments. With reference to FIGS. 1A-3 , the method 300 may be implemented in hardware components and/or software components of the mobile computing device (e.g., 100, 200 in FIGS. 1A-2 ), the operation of which may be controlled by one or more processors (e.g., the general-purpose processor 206) of the mobile computing device. In order to encompass the alternative configurations enabled in various embodiments, the hardware implementing the method 300 is referred to herein as a “processing device.”

In block 302, the processing device may receive a first input from a first touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ). In some embodiments, a user may interact with a surface or area (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device having the first touch sensor. The user interaction with the first touch sensor may trigger a response by the processing device or a microcontroller (e.g., microcontroller 228 in FIG. 2 ) associated with the first touch sensor. The response may include signals or data configured to indicate qualities of the user interactions with the first touch sensor, such as location, area, duration, direction, speed, pressure, number, frequency, or sequence of interactions with the touch sensor. In some embodiments, the processing device may be configured to derive some such qualities of the user interactions with the first touch sensor from other qualities of the user interactions with the first touch sensor, as described further herein with reference to the method 800 in FIG. 8 . The processing device may receive the signals or data configured to indicate qualities of the user interactions with the first touch sensor.

In block 304, the processing device may identify a first type of the user interaction with the first touch sensor from the first input. Based on an analysis of the received first input, the processing device may identify characteristics of the user interaction with the first touch sensor that may indicate the type and/or a quality of the user interaction with the first touch sensor. The types and/or qualities of the user interactions with the first touch sensor may be derived using various techniques, algorithms, or heuristics. For example, identifying a first type of user interaction with the first touch sensor from the first input may include identifying a first quality of a plurality of received inputs including the first input, and identifying the first type of user interaction having the first quality of the plurality of received inputs including the first input. As another example, identifying a first type of user interaction with the first touch sensor from the first input may include identifying a first quality of a plurality of received inputs including the first input, deriving a second quality from the first quality of the plurality of received inputs, and identifying the first type of user interaction having the second quality. These and further examples of analysis of the analysis of the received first input that may be executed are described further herein with reference to block 802 of the method 800 illustrated in FIG. 8 .

Multiple non-exhaustive or limiting examples of types and/or a qualities for the user interaction with the first touch sensor that the processing device may identify include: a tap; a strong tap; a quick tap; multiple taps; a location of a tap; a press; a duration of a press; a pressure of a press; a location of a press; a swipe; a single finger swipe; a multiple finger swipe; a speed of a swipe, a length of a swipe, a location of a swipe; a gesture; a shape of the gesture; a hover; a height of a hover; a duration of a hover; a location of a hover; a grip; a handedness of a grip, a number of hands or fingers used for a grip, a location of a grip; a pressure of a grip; or an area of a grip; and a part of a body or object used to make the interaction.

In block 306, the processing device may identify a first sensor input data in a multisensor input data structure corresponding with the first type of user interaction. As described further herein, the mobile computing device may include a multisensor input data structure (e.g., multisensor input translation table 1100 of FIG. 11 ) configured to relate the combinations of a user interactions with touch sensors with multisensor input responses (e.g., action data in columns 1116, 1118 of FIG. 11 ). The multisensor input data structure may include sensor input data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) that may represent the interactions with the touch sensors, including qualities and/or types of the interactions with the touch sensors. For example, to identify a first sensor input data in a multisensor input data structure corresponding with the first type of user interaction, the processing device may compare the first type of user interaction with a plurality of sensor input data associated with the first touch sensor, and may identify the first sensor input data from the plurality of sensor input data associated with the first touch sensor that matches the first type of user interaction. To determine whether the received first input matches a first sensor input data for a multisensor input, the processing device may compare the qualities and/or types of the user interactions with the first touch sensor of the received first input and the sensor input data in the multisensor input data structure. The processing device may determine whether the qualities and/or types of the user interactions with the first touch sensors of the received first input matches any of the sensor input data.

In block 308, the processing device may receive a second input from a second touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ). In some embodiments, a user may interact with a surface or area (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device having the second touch sensor. The user interaction with the second touch sensor may trigger a response by the processing device or a microcontroller (e.g., microcontroller 228 in FIG. 2 ) associated with the second touch sensor. The response may include signals or data configured to indicate qualities of the user interactions with the second touch sensor, such as location, area, duration, direction, speed, pressure, number, frequency, or sequence of interactions with the touch sensor. In some embodiments, the processing device may be configured to derive some such qualities of the user interactions with the second touch sensor from other qualities of the user interactions with the second touch sensor, as described further herein with reference to the method 800 in FIG. 8 . The processing device may receive the signals or data configured to indicate qualities of the user interactions with the second touch sensor. In some embodiments and situations, receiving a first input from a first touch sensor in block 302 and receiving a second input from a second touch sensor in block 308 may include receiving the first input and the second input concurrently.

In block 310, the processing device may identify a second type of the user interaction with the second touch sensor from the second input. Based on an analysis of the received second input, the processing device may identify characteristics of the user interaction with the second touch sensor that may indicate the type and/or a quality of the user interaction with the second touch sensor. The types and/or qualities of the user interactions with the second touch sensor may be derived using various techniques, algorithms, or heuristics. The analysis of the analysis of the received second input may be executed as described further herein with reference to block 802 of the method 800 in FIG. 8

Multiple non-exhaustive or limiting examples of types and/or a qualities for the user interaction with the second touch sensor that the processing device may identify include: a tap; a strong tap; a quick tap; multiple taps; a location of a tap; a press; a duration of a press; a pressure of a press; a location of a press; a swipe; a single finger swipe; a multiple finger swipe; a speed of a swipe, a length of a swipe, a location of a swipe; a gesture; a shape of the gesture; a hover; a height of a hover; a duration of a hover; a location of a hover; a grip; a handedness of a grip, a number of hands or fingers used for a grip, a location of a grip; a pressure of a grip; or an area of a grip; and a part of a body or object used to make the interaction.

In block 312, the processing device may identify a second sensor input data in a multisensor input data structure corresponding with the second type of user interaction. As described further herein, the mobile computing device may include a multisensor input data structure (e.g., multisensor input translation table 1100 of FIG. 11 ) configured to relate the combinations of a user interactions with touch sensors with multisensor input responses (e.g., action data in columns 1116, 1118 of FIG. 11 ). The multisensor input data structure may include sensor input data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) that may represent the interactions with the touch sensors, including qualities and/or types of the interactions with the touch sensors. To determine whether the received second input matches a second sensor input data for a multisensor input, the processing device may compare the qualities and/or types of the user interactions with the second touch sensor of the received second input and the sensor input data in the multisensor input data structure. The processing device may determine whether the qualities and/or types of the user interactions with the second touch sensors of the received second input matches any of the sensor input data.

In block 314, the processing device may determine whether the first input and the second input combine as a multisensor input in an entry in the multisensor input data structure having the first sensor input data and the second sensor input data related to a multisensor input response. From matching the received first and second inputs with the first and second sensor input data in the multisensor input data structure, the processing device may identify the entries in the multisensor input data structure having the first and second sensor input data for the received first and second inputs. The entry having the first and second sensor input data for the received first and second inputs may correspond to multisensor inputs defined by the first and second sensor input data for the entry. The processing device may then execute the multisensor input response in response to determining that the first input and the second input combine as the multisensor input in the entry in the multisensor input data structure having the first sensor input data and the second sensor input data related to the multisensor input response.

In some embodiments, the processing device may determine whether the second input is received during a multisensor input sequence duration from receiving the first input in block 308, and perform the operations in blocks 310-314 as described above in response to determining that the second input is received during the multisensor input sequence duration from receiving the first input.

FIG. 4 illustrates a method of enabling a multisensor input mode for managing multisensor inputs according to various embodiments. With reference to FIGS. 1A-4 , the method 400 may be implemented in hardware components and/or software components of the mobile computing device (e.g., 100, 200 in FIGS. 1A-2 ), the operation of which may be controlled by one or more processors (e.g., the general-purpose processor 206) of the mobile computing device. In order to encompass the alternative configurations enabled in various embodiments, the hardware implementing the method 400 is referred to herein as a “processing device.”

In various embodiments processing of a first input from a first touch sensor may be enabled on the mobile computing device, such as in a normal input mode configured to process inputs from a set of most frequently use touch sensors, such as a touchscreen (e.g., touch sensor 102 in FIG. 1A, touchscreen 226 in FIG. 2 ).

In block 402, the processing device may detect a trigger for a multisensor input mode. The multisensor input mode may be configured to enable processing of user interactions with touch sensors (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ) that otherwise may not be enabled to detect some or any user interaction. Such touch sensors may include capacitive inputs sensors of surfaces or areas (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device that are not the front or touchscreen of the mobile computing device.

In some embodiments, the trigger may be a received input from a user interaction with a touch sensor, including a touch sensor configured to detect a specific user interaction to trigger the multisensor input mode but that otherwise may not be enabled to detect some or any other user interaction. For example, a unique grip for which the user places the middle and index finger close together, which is not the normal way for holding the mobile computing device. In another example, a unique tap or back/side gesture may trigger listening for other back/side gestures. In other words, the processing device may only be watching for a hard back tap, which is not normally associated with a standard holding grip. Once this unique tap is identified, then the processing device may start listening for other kinds of back/side touches.

In some embodiments, the trigger may be a signal or data received by the processing device representing a device parameter, which may be referred to as device parameter data. The device parameter data may represent any number and combination of mobile computing device parameters other than interactions with a touch sensor. For example, device parameter data may include readings or signals from other sensors of the mobile computing device, such as a light sensor, an accelerometer, a gyroscope, a temperature sensor, a voltage and/or current sensor, an infrared sensor, etc. Device parameter data may include location data of the mobile computing device, such as global positioning system (GPS) data. Device parameter data may include wired or wireless connection data of the mobile computing device, such as cellular, Wi-Fi, Bluetooth, near-filed communication (NFC), etc., or wired peripheral device connection data, including status of a connection or identification of a device to which the mobile computing device is connected. Device parameter data may include mobile computing device state data, such as a power state (e.g., full, low, charging, specific battery charge or power level, etc.) or an activity state (e.g., active, sleep, hibernate, etc.) of the mobile computing device.

In some embodiments, the trigger may include a signal or instruction processed by the processing device as part of implementation of an application executing on the mobile computing device. In some embodiments, the trigger may be a number or combination of received inputs, device parameters, or application related signals or instructions.

In block 404, the processing device may enter a multisensor input mode in response to detecting the trigger. The processing device may determine and load multisensor input data structures (e.g., multisensor input translation table 1100 of FIG. 11 ) configured to interpret user interactions with the multiple touch sensor inputs of the mobile computing device.

In some embodiments, the processing device may enter the multisensor input mode for different purposes depending on the trigger received, which may prompt the processing device to determine and load a multisensor input data structure associated with the specific purpose. For example, a mobile computing device front down on a surface in combination with different user interactions with a touch sensor on a back of the mobile computing device may trigger the multisensor input mode for different purposes. A tap on the touch sensor may activate a home assistant application, while a swipe along a vertical axis of the touch sensor may adjust the volume of a speaker of the mobile computing device. In another example, if the ambient brightness is very high and different from when a display brightness was last set, user interactions with a touch sensor may adjust the display brightness level.

In block 406, the processing device may enable processing of a second input from a second touch sensor. The processing device may enable a second touch sensor to detect inputs it could not previously detect and/or the processing device to processes inputs from the second touch sensor for which the processing device did not previously process inputs. In some embodiments, a second touch sensor may be activated, more frequently monitored, enabled to send inputs to the processing device, or increased in sensitivity, any of which may include enabling a microcontroller (e.g., microcontroller 228 in FIG. 2 ) or features of a microcontroller associated with the second touch sensor. In some embodiments, the processing device may enable itself to process all or more inputs received from the second touch sensor, or monitor or increase monitoring of the second touch sensor.

After enabling a second touch sensor to detect inputs it could not previously detect and/or the processing device to processes inputs from the touch sensor for which the processing device did not previously process inputs, the processing device may receive a first input from a first touch sensor in block 602 as described for the like numbered block of the method 600 with reference to FIG. 6 or the method 900 with reference to FIG. 9 . Alternatively, the processing device may receive a first input from a first touch sensor and a second input from a second touch sensor in block 702 as described for the like numbered block of the method 700 with reference to FIG. 7 .

FIG. 5 illustrates a method 500 of integrating multi-touch inputs across multiple distinct surfaces of a mobile computing device according to various embodiments. With reference to FIGS. 1A-5 , the operations of the method 500 may be implemented in hardware components and/or software components of the mobile computing device (e.g., 100, 200), the operation of which may be controlled by one or more processors (e.g., the general-purpose processor 206 and/or the microcontroller 228) of the mobile computing device.

In block 510, the processor may receive a multisensor input from at least one touch sensor on the mobile computing device distinct from a touchscreen of the mobile computing device. For example, a user touching a touch sensor on the mobile computing device, may cause a change in touch sensor state, such as capacitance, measured by the touch sensor.

The processor may receive the measured change in touch sensor state as a multisensor input. The received measurements may reflect characteristics of various types of input including a duration of contact, a number of contact points, a size of the contact point(s), a sequence or contiguous series of contacts, a pattern of simultaneous contacts, and a level of pressure or force applied during the contact. For example, as part of gripping the mobile computing device, a user touching a back-panel touch sensor, located on a back housing (e.g., rear area 114) of the mobile computing device, may cause a recognizable change in touch sensor state associated with a gripping event. As a further example, a user making a gesture on the back-panel touch sensor, like a curved swipe across a portion of the back housing, may cause a different recognizable change in touch sensor state associated with that gesture.

In block 520, the processor may determine an operational context of the mobile computing device using contextual awareness data. Contextual awareness data may include information from various sources helpful for defining the circumstances that form the setting (i.e., the operational context) in which the multisensor input(s) are received.

A multisensor input may be intended by a user to execute a first operation in a first operational context, but in a second operational context not to execute the first operation and/or to execute a second operation. For example, the processor may utilize cues from contextual awareness data to trigger a more comprehensive detection mode for multi-surface touches.

Multi-surface touches may include contact with touch sensor on different sides of the mobile computing device. For example, an application currently active on a display of the touchscreen make available additional functions or change a touch sensor detection mode of the mobile computing device.

Likewise, a position, orientation, and/or movement of the mobile computing device may provide a trigger to make available additional functions or change a touch sensor detection mode of the mobile computing device. For example, laying the mobile computing device facing flat on a table may trigger a detection mode for multi-surface touches or changes in the detection mode. Also, shaking the mobile computing device may trigger a mode that allows the user to use multi-surface touches to execute functions. As a further example, a processor may utilize environmental characteristics to trigger a particular detection mode of multi-surface touches. For example, if ambient brightness is very high and different from when the display brightness was last set, then a detected touch or movement on a back touch sensor may translate to an adjustment in brightness level.

In block 530, the processor may determine a function (e.g., a first function) associated with the multisensor input received in block 510 and the operational context determined in block 520. The determination in block 530 may involve identifying or selecting a particular multisensor input translation table or set of tables that is/are appropriate for use for the determined operational context. The appropriate multisensor input translation table(s) may provide a correlation between the multisensor input(s) receive from one or more touch sensors, and a function the processor may perform or causes another component of the mobile computing device to perform. The processor may obtain the particular translation table(s) from memory (e.g., 214 in FIG. 2 ). Alternatively or additionally, the determination in block 530 may involve cascading rules set and/or parametric method that applies the determined operational context and the received multisensor input to determine the function.

In block 540, the processor may execute an operation configured to cause the mobile computing device to perform the function determined in block 530. The executed operation may change settings controlling touch sensors, change which multisensor input translation table is used, or change a function associated with touch sensors. For example, when a user performs a first “trigger” gesture on the back of the mobile computing device that the processor recognizes, within a predetermined period the processor may receive a shortcut gesture configured to launch a particular application on the mobile computing device, in the next few seconds. Additionally or alternatively, the executed operation may change other settings of the mobile computing device. Further, the executed operations may transmit a message and/or instruction to another component for executing the determined function. For example, to perform operations associated with the mobile computing device generally and/or applications active on the mobile computing device.

In some embodiments, the processor may repeat the operations of the method 500 to map further touch sensor readings to application functions for a mobile computing device. Executing the operations of the method 500 may change the operational context, thus changing or making available additional functions associated with received multisensor inputs. For example, the multisensor input received in block 510 may represent a unique grip on the mobile computing device, like the user placing the middle and index finger close together, which is not the normal way of holding the mobile computing device.

In addition, an operational context of the mobile computing device may include a state in which multi-surface contact is not recognized as an input function (i.e., multi-surface controls are off). In this way, receiving multisensor inputs corresponding to the unique grip when multi-surface controls are off may trigger an operation in block 540 that turns multi-surface controls on.

As another example, the multisensor input received in block 510 may represent a unique tap or back/side gesture configured to unlock other back/side gestures. In this way, the device may be configured to monitor for a hard back-tap (which is not normally associated with a standard holding grip). Once such a hard back-tap is identified, the processor may monitor for other kinds of back/side touches that trigger recently unavailable functions. Similarly, a unique tap or back/side gesture may trigger the processor to listen for other subsequent back/side gestures. For example, the processor may always monitor for a particular touch profile, like from a hard tap on a back of the mobile computing device, which is not normally associated with a standard grip on the device. Once that particular touch profile is detected, then the processor may start monitoring for other kinds of touch profiles.

The processor may repeat the operations of the method 500 in response to receipt of additional multisensor inputs in block 510. As another example, the processor may repeat the operations of the method 500 for a predefined number of iterations or a predefined period indicated in parameters associated with an active application on the mobile computing device.

In various embodiments, the descriptions herein with reference to the methods 600, 700, 800, 900 in FIGS. 6-9 provide further descriptions, features, and embodiments of and/or relating to the methods 300, 400 described with reference to in FIGS. 3 and 4 .

FIG. 6 illustrates a method of managing multisensor inputs received in sequence according to various embodiments. With reference to FIGS. 1A-6 , the method 600 may be implemented in hardware components and/or software components of the mobile computing device (e.g., 100, 200 in FIGS. 1A-2 ), the operation of which may be controlled by one or more processors (e.g., the general-purpose processor 206) of the mobile computing device. In order to encompass the alternative configurations enabled in various embodiments, the hardware implementing the method 600 is referred to herein as a “processing device.”

In block 602, the processing device may receive a first input from a first touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ). In some embodiments, a user may interact with a surface or area (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device having a touch sensor. The user interaction with a touch sensor may trigger a response by the processing device or a microcontroller (e.g., microcontroller 228 in FIG. 2 ) associated with the touch sensor. The response may include signals or data configured to indicate qualities of the interactions with the touch sensor, such as location, area, duration, direction, speed, pressure, number, frequency, or sequence of interactions with the touch sensor. In some embodiments, the processing device may be configured to derive some such qualities of the interactions with the touch sensor from other qualities of the interactions with the touch sensor, as described further herein with reference to the method 800 in FIG. 8 . The processing device may receive the signals or data configured to indicate qualities of the interactions with the touch sensor.

In determination block 604, the processing device may determine whether the first input from the first touch sensor is a potential part of a multisensor input. In some embodiments, a multisensor input may be a combination of a user interaction with a first touch sensor and a user interaction with a second touch sensor. Specific combinations of a user interaction with a first touch sensor and a user interaction with a second touch sensor may define a multisensor input by being associated with a multisensor input response to the multisensor input.

In some embodiments, definitions of multisensor inputs may be stored on the mobile computing device in a memory (e.g., memory 214 of FIG. 2 ) of the mobile computing device. For example, the definitions of multisensor inputs may be stored in a multisensor input data structure (e.g., multisensor input translation table 1100 of FIG. 11 ) configured to relate the combinations of a user interaction with a first touch sensor and a user interaction with a second touch sensor with multisensor input responses.

To determine whether the first input is a potential part of a multisensor input in determination block 604, the processing device may compare the first input with data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) in the multisensor input data structure associated with the first touch sensor. It is possible that the first input may be determined to be part of any number of multisensor inputs, but subsequent second inputs from a second touch sensor may not fit the definitions of a multisensory input in combination with the first input. Therefore, it may be that the first input is determined to be a potential part of a multisensor input, because it may be uncertain that the second input of a multisensor input will succeed the first input. In such circumstances, the first input may not be combined with the second input to trigger a multisensor input response, described further here in with reference to block 612.

In response to determining that the first input from the first touch sensor is not a potential part of a multisensor input (i.e., determination block 604=“No”), the processing device may determine that the first input is a single sensor input in block 612. The processing device may not identify the first input in a definition of a multisensor input in determination block 604. As such, there may not be any need to continue to determine whether a successive second input from a second touch sensor in combination with the first input combine to make a multisensor input. Therefore, the processing device may classify the first input as a single sensor input and terminate the instance of the method 600 triggered by receiving the first input from a first touch sensor in block 602.

In response to determining that the first input from the first touch sensor is a potential part of a multisensor input (i.e., determination block 604=“Yes”), the processing device may wait for a second input from a second touch sensor in block 608. In some cases, the multisensor input may be a combination of the first user interaction with the first touch sensor and the second user interaction with the second touch sensor in a sequence within a multisensor input sequence duration. The multisensor input sequence duration may represent a designated period, such as time, transistor flops, etc., from receiving the first input during which the processing device may receive the second input. The processing device may wait the multisensor input sequence duration before responding to the first input to allow the user an opportunity to interact with the second touch sensor to implement a multisensor input as a sequence of inputs on the first and second touch sensors.

In determination block 610, the processing device may determine whether the second input from the second touch sensor is received during the multisensor input sequence duration. In some embodiments, the processing device may receive the second input during the multisensor input sequence duration, and in some embodiments, the multisensor input sequence duration may expire before the processing device receives a second input.

Inputs received after the multisensor input sequence duration may be treated as new first inputs. Thus, in response to determining that the second input from the second touch sensor is not received during the multisensor input sequence duration (i.e., determination block 610=“No”), the processing device may determine that the first input is a single sensor input in block 612 as described herein.

In some embodiments, the processing device may receive a second input from a second touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ) in block 606 at any time after receiving the first input from the first touch sensor in block 602 and before determining that the second input from the second touch sensor is not received during the multisensor input sequence duration in determination block 610. In some embodiments, a user may interact with a second surface or second area (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device having a second touch sensor. The user interaction with the second touch sensor may trigger a response in the same manner as described with reference to block 602.

In some embodiments, the processing device may run multiple instances of the method 600 in parallel, and the second input received in block 606 in other instances of the method 600 may be handled as the first instance received in block 602.

After receiving the second input from the second touch sensor in block 606 and in response to determining that the second input from the second touch sensor is received during the multisensor input sequence duration (i.e., determination block 610=“Yes”), the processing device may determine whether the first input from the first touch sensor and the second input from the second touch sensor combine as a multisensor input in determination block 614. Similar to determining whether the first input is a potential part of a multisensor input in determination block 604, the processing device may use the multisensor input data structure configured to relate combinations of user interactions with a first touch sensor and a second touch sensor with multisensor input responses to determine whether the second input combines with the first input as a multisensor input. In some embodiments, the processing device may compare the second input with data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) in the multisensor input data structure to determine whether the second input matches any entries of the multisensor input data structure, and compare the entries with entries that match the first input identified in determination block 604. In some embodiments, the processing device may compare the second input with data in the entries of the multisensor input data structure that match the first input identified in determination block 604. Matching entries for the first input and the second input or data for the second input in entries for the first input may indicate that the first input and the second input define a multisensor input in the multisensor input data structure. No matching entries for the first input and the second input or data for the second input in entries for the first input may indicate that the first input and the second input do not define a multisensor input in the multisensor input data structure.

In response to determining that the first input from the first touch sensor and the second input from the second touch sensor do not combine as a multisensor input (i.e., determination block 614=“No”), the processing device may determine that the first input and the second input are single sensor inputs in block 616. Similar to determining that the first input is a single sensor input in block 612, the processing device may not identify the combination of the first input and the second input in a definition of a multisensor input in determination block 614. As such, there may not be any need to continue implementing the method 600 for the combination of the first input and the second input. Therefore, the processing device may classify the first input and the second input as single sensor inputs and terminate the instance of the method 600 triggered by receiving the first input from a first touch sensor in block 602.

In response to determining that the first input from the first touch sensor and the second input from the second touch sensor do combine as a multisensor input (i.e., determination block 614=“Yes”), the processing device may execute a multisensor input response in block 618. As described herein, the multisensor input data structure may relate the multisensor input and a multisensor input response. The processing device may execute code (e.g., action data in columns 1116, 1118 in FIG. 11 ) of the multisensor input response from the multisensor input data structure or referenced to (e.g., action data in columns 1116, 1118 in FIG. 11 ) from the multisensor input data structure.

FIG. 7 illustrates a method of managing multisensor inputs received simultaneously according to various embodiments. With reference to FIGS. 1A-7 , the method 700 may be implemented in hardware components and/or software components of the mobile computing device (e.g., 100, 200 in FIGS. 1A-2 ), the operation of which may be controlled by one or more processors (e.g., the general-purpose processor 206) of the mobile computing device. In order to encompass the alternative configurations enabled in various embodiments, the hardware implementing the method 700 is referred to herein as a “processing device.”

In some embodiments, blocks 616 and 618 may be implemented in manners similar to those for like numbered blocks of the method 600 described with reference to in FIG. 6 .

In block 702, the processing device may receive a first input from a first touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ) and a second input from a second touch sensor (e.g., touch sensor 102, 104, 106, 108, 227 in FIGS. 1A-2 ). In some embodiments, a user may interact with multiple surfaces or areas (e.g., front area 112, rear area 114, sides 116 a, 116 b, and top area 118 in FIGS. 1A and 1B) of the mobile computing device having touch sensors. The user interactions with the touch sensors may trigger responses by the processing device or microcontrollers (e.g., microcontroller 228 in FIG. 2 ) associated with the touch sensors. The responses may include signals or data configured to indicate qualities of the interactions with the touch sensors, such as location, area, duration, direction, speed, pressure, number, frequency, or sequence of interactions with the touch sensor. In some embodiments, the processing device may be configured to derive some such qualities of the interactions with the touch sensors from other qualities of the interactions with the touch sensor, as described further herein with reference to the method 800 in FIG. 8 . The processing device may receive the signals or data configured to indicate qualities of the interactions with the touch sensors. In some embodiments, the user interactions with the touch sensors may occur simultaneously or concurrently. Similarly, the processing device may receive the first input and the second input simultaneously or concurrently.

In determination block 704, the processing device may determine whether the first input from the first touch sensor and the second input from the second touch sensor combine as a multisensor input. In some embodiments, a multisensor input may be a combination of a user interaction with a first touch sensor and a user interaction with a second touch sensor. Specific combinations of a user interaction with a first touch sensor and a user interaction with a second touch sensor may define a multisensor input by being associated with a multisensor input response to the multisensor input. In some embodiments, definitions of multisensor inputs may be stored on the mobile computing device in a memory (e.g., memory 214 of FIG. 2 ) of the mobile computing device. For example, the definitions of multisensor inputs may be stored in a multisensor input data structure (e.g., multisensor input translation table 1100 of FIG. 11 ) configured to relate the combinations of a user interaction with a first touch sensor and a user interaction with a second touch sensor with multisensor input responses. To determine whether the first input and the second input combine as a multisensor input, the processing device may compare the first input with data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) in the multisensor input data structure associated with the first touch sensor and the second input with data (e.g., sensor input data in columns 1102, 1104, 1106 of FIG. 11 ) in the multisensor input data structure associated with the second touch sensor. In some embodiments, the processing device may compare the first input and the second input with data in the multisensor input data structure to determine whether the first input and the second input match any entries of the multisensor input data structure, and compare the entries for the first input and the entries for the second input with each other to find matching entries. In some embodiments, the processing device may compare the second input with data in the entries of the multisensor input data structure that match the first input. Matching entries for the first input and the second input or data for the second input in entries for the first input may indicate that the first input and the second input define a multisensor input in the multisensor input data structure. It is possible that either the first input and/or the second may be identified as part of any number of multisensor inputs, but not for the same definition of a multisensory input in combination. No matching entries for the first input and the second input or data for the second input in entries for the first input may indicate that the first input and the second input do not define a multisensor input in the multisensor input data structure.

The processor may determine an action to execute from the action data in a column 1116, 1118 of the row 1120, 1122, 1124, 1126, 1128, 1130 based on any combination of the device parameter data, the application data, or the action data in any combination of columns 1108, 1110, 1112, 1114, 1116, 1118 of the row 1120, 1122, 1124, 1126, 1128, 1130.

In some embodiments, the application data associated with a combination of sensor input data in a row 1120, 1122, 1124, 1126, 1128, 1130 of a multisensor input translation table 1100 may be augmented with additional columns 1112, 1114 or overwritten. For example, a running application may be associated with an action in response to a combination of sensor input data. The application data for the running application may be added to a row 1120, 1122, 1124, 1126, 1128, 1130 of the multisensor input translation table 1100 having the combination of sensor input data by adding a column 1112, 1114. In another example, a running application may preempt action in response to a combination of sensor input data for other applications, and the combination of sensor input data in a row 1120, 1122, 1124, 1126, 1128, 1130 of the multisensor input translation table 1100 may be associated with the running application; and disassociated with another application by overwriting the application data of the other application with the application data of the running application. In other words, a running application may preempt action in response to a combination of sensor input data for another application with application data in the multisensor input translation table 1100 by replacing the application data for the other application in the multisensor input translation table 1100 with application data for the running application.

In some embodiments, the device parameter data or the action data associated with a combination of sensor input data in a row 1120, 1122, 1124, 1126, 1128, 1130 of the multisensor input translation table 1100 may be expanded with additional columns 1108, 1110, 1116, 1118 or overwritten based on the application data in the row 1120, 1122, 1124, 1126, 1128, 1130. Similar to the application data addition examples, the device parameter data or the action data associated may be associated with a combination of sensor input data and an application data in a row 1120, 1122, 1124, 1126, 1128, 1130 of the multisensor input translation table 1100. The device parameter data or the action data associated with a running application may be added to a row 1120, 1122, 1124, 1126, 1128, 1130 of the multisensor input translation table 1100 having the combination of sensor input data and the application data by adding a column 1108, 1110, 1116, 1118.

In embodiments in which the running application preempts action for other applications, the device parameter data or the action data for the running application may be associated with the combination of sensor input data and running application data in a row 1120, 1122, 1124, 1126, 1128, 1130; and the device parameter data or the action data for the other application may be disassociated from the combination of sensor input data and running application data in a row 1120, 1122, 1124, 1126, 1128, 1130 by overwriting the device parameter data or the action data with the device parameter data or the action data of the running application.

In various embodiments, new application data, device parameter data, or action data associated with a combination of sensor input data in a row 1120, 1122, 1124, 1126, 1128, 1130, already containing application data, device parameter data, or action data, may be added to the multisensor input translation table 1100 by adding a new row associating the combination of sensor input data with the new application data, device parameter data, or action data. In some embodiments, multiple multisensor input translation tables 1100 may be implemented for various inputs from combinations of touch sensors, sets of device parameters, applications, or sets of actions. In some embodiments, the multisensor input translation table 1100 may be stored on, loaded to, or accessed from a memory (e.g., memory 214 of FIG. 2 ) of the mobile computing device by the processor, such memory including a non-volatile storage memory, a volatile main memory, such as a random access memory (RAM), and/or a volatile cache memory.

In various embodiments, an operational context of the mobile computing device may be determined using contextual awareness data. A processor may consider the received multisensor inputs in the determined operational context to determine a particular function to execute. An example of determining an operational context of the mobile computing device using contextual awareness data is shown in FIG. 12 . The operational context of the mobile computing device may be determined by combining or fusing, by an inference engine 1201, a plurality of data associated with received inputs, parameters from one or more active applications, and/or state information from one or more components associated with the mobile communication device, such as a multitude of different types of data relevant to conditions under which multisensor inputs are received. In some embodiments, the inference engine 1201 can combine or fuse both real-time and non-real time contextual awareness data associated with conditions under which multisensor inputs are received in order to determine the operational context.

Contextual awareness data may include any suitable type of real-time and/or non-real-time data associated with the mobile computing device, such as, for instance, touchscreen active application parameters 1210, background active application parameters 1220, a touchscreen state 1230, other onboard component(s) state(s) 1240, a peripheral component state 1250, multisensor input details 1260, other sensor inputs 1270, and any other suitable contextual awareness data, and/or any combination thereof. The touchscreen active application parameters 1210 may include a list of available or currently permissible inputs for an application actively controlling all or part of a display on the touchscreen that may be received as a multisensor input. For example, while reading an email (i.e., an active application), if the user turns the mobile computing device sideways and grasps it with two thumbs on the front and supports it on the back, then the touchscreen may immediately change to a landscape keyboard and provide the user interface for receiving inputs that may be used to reply to that email. As another example, front and back touches may be used to complement each other's slightly different affordances. For example, in a text message, a user tapping on the touchscreen may place a cursor at a certain word display where the user tapped. The user may then touch a back surface of the mobile computing device to more finely position the cursor between words or letters. This exploits the relative advantages of each side: Using combinations of front and side touch inputs may be useful to allow a user to find the touch target and then touch it directly. Back touch may enable the user to move a selector or cursor in a fine-grained manner without the finger on the front being in the way. Similarly, with a photo gallery application active, a swipe rearward facing touch sensor may move a highlighted frame among a grid of pictures. Thereafter, a tap gesture may select or show a context menu.

The background active application parameters 1220 may include a list of available or currently permissible inputs for an application actively running on the mobile computing device, but not actively controlling all or part of a display on the touchscreen that may be received as a multisensor input.

The touchscreen state 1230 may provide information regarding whether the touchscreen is on, off, dimmed, or in some other state. For example, with the touchscreen in an off state, received multisensor inputs may be intended for a particular background application. Similarly, other onboard component(s) state(s) 1230, like the remaining charge in a battery of the mobile computing device or whether the mobile computing device is in a power conservation mode, may provide information regarding whether multisensor inputs should be ignored or whether touch sensors, other than the touchscreen, should be turned off.

The peripheral component state 1250 may provide information regarding whether multisensor inputs may be intended to control that peripheral component. For example, if extended reality goggles or an audio headset are operatively coupled to the mobile computing device, received multisensor inputs may be used to control such peripheral components.

The multisensor input details 1260 may include the touch profile associated with the multisensor input and identify which touch sensor(s) or which part of one or more particular touch sensors detected the change in touch sensor state.

The other sensor input 1270 may provide information from other sensors of the mobile communication device that may be used for determining an operational context of the mobile computing device. For example, proximity, orientation, and/or motion sensors may be used to recognize the mobile computing device is face down on a surface, in a pocket, moving, stationary, or in some other situation that may inform a current operational context of the mobile computing device.

In some embodiments, in addition to using contextual awareness data, the inference engine 1201 may use relevant data (e.g., real-time, non-real time, or a combination thereof) that are not only associated with multisensor inputs or determining the operational context. For example, the inference engine 1201 may use real time of day, date, location, and other similar information that may be helpful for determining a current operational context of the mobile computing device.

All this information may be used by an inference engine 1201 to determine a current operational context. For example, inference engine 1201 can generate a contextual assessment corresponding to the determined operational context. The contextual assessment may then be used to determine what to do with received multisensor inputs.

In some embodiments, the inference engine 1201 may utilize a state machine (e.g., deterministic rule based and/or a statistical state machine) to analyze data, e.g., data from available resources such as 1210, 1220, 1230, 1240, 1250, 1260, 1270 and infer decisions on the operational context. The rule base and the statistical state machine of the inference engine 1201 may be trained off line, on-line, or partly off-line and on-line. In addition, the inference engine 1201 may also exchange information with a knowledge support system or other remote data source, in determining the operational context.

FIGS. 13-14D illustrate some examples of contextual awareness data being used to change an operating mode and/or setting of the mobile computing device 100 in accordance with various embodiments.

FIG. 13 illustrates a user carrying the mobile computing device in a front pants pocket. In various embodiments, the processor of the mobile computing device may use contextual awareness data, such as input from sensors of the mobile computing device, to determine an operational context. For example, the processor may determine whether other sensor inputs (e.g., 970 in FIG. 9 ) indicate the mobile computing device is in a put-away state (i.e., an operational context). One or more of the outputs of the other sensors may be compared to one or more thresholds, singularly or in combination, and the one or more of the outputs being above or below the thresholds may indicate the mobile computing device is in a put-away state. As a specific example, a camera sensing a threshold level of darkness for a period time while accelerometer movements are detected may indicate the mobile computing device is in a closed bag or pocket. As another specific example, a microphone output being consistent with the shuffling and muffling sounds typical in a pocket or bag may indicate the mobile computing device is in a pocket or bag.

In some embodiments, the processor of the mobile computing device may be configured to learned various user-designated put-away states, such as through a calibration or registration process in which the user places the mobile computing device in a particular put-away state long enough to enable the processor to gather various sensor data to be correlated to the particular put-away state. Such sensor data may be stored in memory and subsequently used as thresholds for determining when the mobile computing device is in a put-away state.

In response to determining the mobile computing device is in a put-away state, the processor may boost the capacitance of the touch sensors, increasing the likelihood that the touch sensors will detect touch input from a user's finger through the material of the pants or other obstructing elements.

FIGS. 14A-14D illustrate various ways to grip a mobile computing device that may be detected using touch sensors. In various embodiments, a particular type of grip or mobile computing device orientation may be used as contextual awareness data for determining an operational context.

FIG. 14A illustrates a two-handed grip. This two-handed grip may be detected from a touch profile that is consistent with both palms engaging opposed lateral sides of the mobile computing device 100, while fingers are held against a back of the mobile computing device.

FIG. 14B illustrates a one-handed grip, which may be detected from a touch profile that is consistent with only one palm engaging a lateral side of the mobile computing device 100, while fingers extending from that palm are held against a back of the mobile computing device 100.

FIG. 14C illustrates another two-handed grip, with the mobile computing device 100 held sideways. This two-handed grip with landscape orientation may be detected from a touch profile characterized by fingers holding three or more corners of the mobile computing device 100.

FIG. 14D illustrates another one-handed grip, with the mobile computing device 100 held sideways. This one-handed grip with landscape orientation may be detected from a touch profile consistent with only one palm engaging a bottom or top side of the mobile computing device 100, while fingers extending from that palm are held against a back of the mobile computing device.

FIGS. 15-18 illustrate some examples of various gestures that may be detected as a multisensor input and used to cause the mobile computing device (e.g., mobile computing device 100 in FIGS. 1A and 1B) to perform a predetermined function in accordance with various embodiments.

FIG. 15 illustrates a plan view of a user performing a circle gesture on a back of a mobile computing device. A gesture, like a circle or arch shaped gesture, on the back of the mobile computing device may provide a way of launching an application of the mobile computing device, like an audio recording. A user may draw a circle type shape with a finger or stylus to begin recording. Use of this type of gesture may be useful to record classroom lectures, business meetings, and social events. This gesture is also discrete and unobtrusive. Also, other subsequent gestures, like a tap, may be used to toggle between record and pause. Similarly, subsequently drawing a square on the back of the mobile computing device may stop recording. The mobile computing device may vibrate, or provide other visual or haptic signal, to let the user know that recording has started, paused, or stopped. Also, the mobile computing device may vibrate twice when recording is paused or stopped.

FIGS. 16A and 16B illustrates a plan view of a user performing another circle gesture on a back of a mobile computing device for launching an application. For example, while the user has an internet browser application active on the display of the touchscreen, the user may jump directly to another application, like the camera by using a predetermined gesture. The letter may be associated with a name of the application, like drawing a “C” for the camera application to launch. Alternatively or additionally, the user may perform an intermediate gesture (i.e., a “trigger” gesture) on the back of the device, which when recognized, makes available one or more shortcut gestures for launching an app. In various embodiments, a trigger gesture may only last a short period, like a few seconds, after which the shortcut gestures are no longer available.

FIG. 17 illustrates a side perspective view of a user performing a tap or other gesture on a back of a mobile computing device to control an application that is active but not displaying on the touchscreen. When a music player application is active (i.e., playing), and the mobile computing device is face down on a surface, the display may shut-down to conserve battery. In some embodiments, a user may control the music player application using one or more gestures on the back of the mobile computing device. For example, a tap may toggle between play and pause; swiping left and/or right may change to the next or previous song; swiping up and/or down may change volume, etc. In this way, the display does not have to be activated to control the application (i.e., provide music controls).

FIG. 18 illustrates a side perspective view of a user resting a finger (i.e., a non-moving gesture) on a back of a mobile computing device to control an application that is not active. A resting finger, tap, or other gesture may be used to launch another application, like the voice assistant. A processor may use an indicator, like the Flashlight application on the back of the mobile computing device (or color LED light), by making it flash, to show that the voice assistant is listening. Thereafter, the user may ask the voice assistant questions or give commands, like, “What's the weather;” “Call David; “When is my next meeting?;” and “Play my Miles Davis Playlist.”

Various embodiments may use additional gestures or combination of touches to activate features or functions on the mobile computing device. The following lists provides some examples of applications that primarily use the back/side only to provide unique but useful touch interactions:

-   -   Squeeze the edges for actions like triggers, captures, and         selection. For example, squeeze to take a picture or send a         message or content.     -   Swipe down to zoom in (i.e. pull the content closer to the user)         and vice versa     -   From the back of the phone, highlight the “beautify” icon on the         front display, and drag the icon into the viewfinder to apply         the effect. Similar actions for other camera effects.”     -   Swipe down to decrease loudness level and brightness, and vice         versa     -   Swipe horizontally to change out background images (see other         examples in original document on this topic)     -   Coordinating side and back touches: When scrolling text or in         text entry, the left/right side panels could move the cursor         up/down, consistent with the direction of the finger. But back         scrolling (even if at an angle) will move down page by page (or         horizontally).     -   While in 2-handed holding position (such as entering text),         swipe down on the sides to switch text entry keyboards.     -   Grip position and hand (left or right) to launch 1-handed mode,         which can either be on the left or the right (depending on which         hand invoked it) and can be sized according to the size of the         hand that invoked it and can be positioned vertically on the         display according to where the user gripped (a high grip would         position the 1-handed mode to make it easier to reach low; a low         grip would position the 1-handed mode to make it easier to reach         high).     -   When there are multiple applications running, tapping on the         back of device can surface an app up to the foreground: this is         a natural way of pushing content forward and can apply to music         tracks in a playlist and images in a gallery folder. User can         continue to tap on the back to bring the next app in the stack         to the foreground. Tapping on the front while in the app         switcher could do the opposite (push the top app into the         background)     -   Home key replacement: tap on the back to simulate a home key so         that the physical home key can be removed. This could be a         special kind of tap to differentiate from false triggers (e.g.,         strong-tap, double tap, two-finger tap, two-finger time         sequenced tap).     -   Swipe on the back/side to move highlighted frame among a grid of         pictures, then tap to select or show a context menu. Optionally,         press-and-hold the highlighted item from the back to open the         item, or to present a context menu. An item on the context menu         can be selected from the front.     -   Map a smaller scrollable space on the back of device to a larger         region on the front of the display. This region can be sized         based on the size of the hand and reach of the finger.

FIGS. 19A-27B illustrate some examples of additional gestures that may be used to cause the mobile computing device (e.g., mobile computing device 100 in FIGS. 1A and 1B) to perform a predetermined function, in accordance with various embodiments. By providing and using touch sensors on one or more surfaces of the mobile computing device, other than the front where the touchscreen is disposed, a display on the touchscreen may remain unobstructed or less occluded by the user's fingers or hand(s).

FIGS. 19A and 19B illustrate a mobile computing device held by a user in one hand while performing a gesture on a back surface of the mobile computing device with a finger of that hand. In FIGS. 19A and 19B, the photo gallery is an active application displaying pictures on the touchscreen. The one-handed grip of the user and the photo gallery application active on the mobile computing device may define the operational context associated with those conditions. In FIG. 19A, the user, while holding the mobile computing device in one hand (i.e., a left hand) engages an index finger on a back panel of the mobile computing device. Thereafter, by sliding the index finger to the right (in the orientation shown in FIGS. 19A and 19B) along the back panel, the picture displayed from the photo gallery changes. Based on the determined operational context, a particular multisensor translation table may be used to convert characteristics of the sliding motion against the back panel to the operation of changing photographs in the photo gallery. In this way, the pictures remain unobstructed while browsing through the photo gallery. In addition or optionally, using gestures or contact with the touchscreen may move between images, while using gestures or contact on the back panel provides a different function, like zooming-in on a photo.

FIGS. 20A and 20B illustrate a mobile computing device held by a user in one hand while performing a gesture on a back surface of the mobile computing device with a finger of that hand. In accordance with various embodiments, by providing and using touch sensors on one or more surfaces of the mobile computing device, other than the front where the touchscreen is disposed, a display on the touchscreen may remain unobstructed or less occluded by the user's fingers or hand(s). In FIGS. 20A and 20B, an e-mail application is the active application displaying text on the touchscreen. The one-handed grip of the user and the e-mail application active on the mobile computing device may define the operational context associated with those conditions. In FIG. 20A, the user, while holding the mobile computing device in one hand (i.e., a left hand) engages an index finger on a back panel of the mobile computing device. Thereafter, by sliding the index finger to the right (in the orientation shown in FIGS. 20A and 20B) along the back panel, the e-mail displayed advances to another e-mail. Based on the determined operational context, a particular multisensor translation table may be used to convert characteristics of the sliding motion against the back panel to the operation of changing from one e-mail to another. In this way, the text of each e-mail remains unobstructed while browsing through e-mails. Similarly, with other applications, like a calendar, swiping left and/or right on the back panel of the mobile computing device may move to the next/previous day, month, or year. In addition, swiping down on the back panel may access other features, like the Android notification drawer or IOS notifications list. The swipe on the back panel need not start at the top of the mobile computing device, like the top of the touchscreen, which may be hard to reach when holding the device one-handed.

FIGS. 21A and 21B illustrates a user holding the mobile computing device one-handed while tapping a back panel to active a function of an active application. For example, a tap on back panel may take a picture. Alternatively, another gesture, like a squeeze or pinch gesture may take the picture. Swiping in a direction may zoom in/out, allowing one-handed camera use, which is a major advantage. In addition, swipe gestures may be used to adjust focus at different focal lengths, adjust degree of background blur or other segmentation effects, add or adjust face beautification effects, and/or change out a background image.

FIGS. 22A and 22B illustrates a user performing a tap gesture on a back of a mobile computing device to active a function of another active application. While viewing thumbnails in the photo gallery, a user may position an index finger behind a particular thumbnail and tap on the back panel, which may pop the thumbnail forward, or make it stand out, like enlarged relative to other thumbnails. Alternatively, an initial touch on the back panel may highlight a corresponding thumbnail or otherwise provide users with a visual indication of where their finger is on the back panel before they tap to enlarge or bring the thumbnail forward. Optionally, holding the finger at that location may trigger an advanced options menu for that picture to be presented. User may select one of the options with a front touch. The same principal may be used to “preview” a video or other content. The user may open the previewed video by selecting it using a front finger (e.g., the thumb) to touch the touchscreen.

FIGS. 23A and 23B illustrates a user performing a tap gesture on a back of a mobile computing device to active yet another function of another active application. The user may place the index finger behind an email message (i.e., on the back panel), press and hold from the back, and an options menu for that message may pop up. User may select one of the options using the front finger. A similar feature may be provided for a contact on the contact list, or a song from the music player.

FIGS. 24A and 24B illustrates a user performing a tap gesture on a back of a mobile computing device to active general functions of the mobile computing device. For example, on mobile computing devices without a “Home key,” a simple unique tap on the back panel may activate the Home screen of the device. Similarly, a simple unique tap on the back may bring up a task switcher menu, which may allow the user to scroll between applications using back swipes. Also, a simple unique tap on the back may capture a selfie or regular photo.

FIGS. 25A and 25B illustrates a user performing a tap gesture on a back of a mobile computing device to active functions of an active application on the mobile computing device. For example, call features, like a simple unique tap on the back may Mute/Un-mute a call or switch calls. An up/down swipe on the back may increase/lower the volume. A single finger up/down swipe on the back may scroll through content (or menus) at a normal speed, while a two finger up/down swipe may advance more quickly. A unique tap followed by a downward swipe from the top (or at least in a downward direction) may pull down a notification tray/list.

FIGS. 26A and 26B illustrates a user performing a tap gesture on a back of a mobile computing device to active functions of an active application on the mobile computing device. While a map application is active, a touch point on the map with thumb on the display of the mobile computing device, to provide an anchor point. Then, a swipe with index finger on the back panel may zoom in and/or out of the anchor point. Similarly, a gallery zoom function may be provided for zooming in and out on images in the Gallery.

FIGS. 27A and 27B illustrates a user performing another gesture on a side panel of a mobile computing device to control application features or general functions of the mobile computing device. For example, when the display on the touchscreen turns off, the luminance may be recorded. When the touchscreen turns on again, the processor may check for a big change in luminance. If a big change is detected, then the mobile computing device may allow the user to adjust brightness by sliding the finger up and down the side. The mobile computing device may support this type of control for a brief period, like a few minutes, when the display has turned back on.

FIGS. 28A-30B illustrate some examples of combination gestures, touching the front and back/side surfaces to cause the mobile computing device (e.g., mobile computing device 100 in FIGS. 1A and 1B) to perform a predetermined function, in accordance with various embodiments. Various embodiments use back and side inputs in coordination with front inputs to result in device actions. Specifically, combinations of touches (to different parts of the device) may constrain the meaning of the touch. This may include both simultaneous use of inputs to the front versus sides/back of the mobile computing device and sequential use of inputs to the front versus sides/back of the mobile computing device, wherein the behaviors of the mobile computing device are dependent upon these combinations of touches.

Various embodiments may include configurations in which an interaction on the back panel or sides of the device serves as a persistent “mode changer,” such that while that touch is happening on the back of the device, the behaviors of the phone that occur as a result of certain (or all) touch types to the front of the phone are altered from their usual response. For example:

-   -   Only while two fingers are placed flat on the back of the screen         adjacent and touching one another laterally can strong taps to         the front of the device be interpreted as an intent to launch         into a deeper functionality within an app.     -   Only while two fingers are placed flat on the back of the screen         adjacent and touching one another laterally can active gestures         (e.g., swiping in the shape of a “C”) to the front of the device         be interpreted as triggers for special features (e.g., shortcuts         to launching an app such as contacts) rather than as regular         swipes.     -   Only while two fingers are placed flat on the back of the screen         adjacent and touching one another laterally will the device be         in a privacy mode. In this mode, private apps are hidden from         view, content from specific users can be hidden and pictures of         certain categories are hidden. For example, while in this         privacy mode (as a result of the persistent touching style to         the back of the device), a touch to the gallery icon would         result in a different appearance of thumbnails than would         otherwise occur (because the images will be screened in privacy         mode).

Various embodiments may include configurations where an interaction on the back panel (or sides of the device) serves as “mode changer” for some temporary period of time. This period of time could be until a particular touch is performed on the front of the device or it could be for a pre-specified time period. For example:

-   -   A strong tap to the back of the phone could result in a         thumbnail style picture of all the open apps. Subsequently, the         user could select any apps they want to close by touching them.         A strong tap to the front of the device could then result in         leaving this deletion mode (with only the unselected apps left         open in the stack) and the screen returning to a full screen         view of the strong-tapped app. In this case the strong tap to         the front of the screen ended the mode that was brought about by         a strong tap to the back of the screen.     -   A strong tap to the back of the device puts the phone into a         temporary mode where it silences all alerts and calls until your         GPS position moves above some threshold. Until your phone moves         to a different region (as determined by GPS motion) or until the         phone back is tapped again, it will continue to silence all         alerts and calls. This could be useful for silencing one's phone         just for a meeting or just while at a movie without having to         remember to turn it back up later.     -   A strong tap to the back of the device triggers the phone to         monitor for active gestures to the front of the phone for 10         seconds. For example, after strong tapping the back of the         phone, the user could then swipe in an arc and then a line         toward the hand to trigger the flashlight to come on. This         gesture to the front of the phone would not trigger the         flashlight under normal circumstances—only when the strong tap         has recently been received from the front of the device. If no         gesture is received within the 10 second window after the strong         tap, then the device stops monitoring for this (or any other)         special gesture.     -   A strong tap to the front of the device leads a cursor to         appear, and now the user can control the position of the cursor         using finger movements on the back of the device.

Various embodiments may include configurations in which simultaneous (or near simultaneous) touches to any combination of front/back and sides creates a specific reaction from the device that is different than the response to any of the component touches alone. For example:

-   -   Holding the phone with two fingers flat on the back of the         screen and touching one another laterally and with the thumb         flat on the front of the device could trigger a one-handed mode.     -   Holding the phone with the thumb across the front of the screen         and with the index finger balled up against the back of device         could trigger the screen to split so that two apps can be         utilized at once.

The various embodiments above may also include aspects that provide a different context for interpretation of that combined touch indications. For example:

-   -   While reading an email, if the user turns the mobile computing         device sideways and grasps it with two thumbs on the front and         supports it on the back, then the screen may immediately change         to a landscape keyboard and the user interface may replying to         that email.     -   Using front and back touches to complement each other's slightly         different affordances. For example, while creating a text entry,         the user may tap on the front of the display to place the cursor         at a certain word. Back touch is then used for finely         positioning the cursor between two letters within that word.         This exploits the relative advantages of each side that the         front side touch is useful as it allows the user to find the         touch target and then touch it directly. The back touch allows         the user to move a selector or cursor in a fine-grained manner         without the finger on the front being in the way.     -   While the photo gallery application is active, a swipe on the         back panel may move a highlighted frame among a grid of         pictures, then a tap may select or show a context menu.

FIGS. 28A and 28B illustrates a user performing a combination of gestures, one on the back panel and another on the touchscreen of the mobile computing device to perform certain functions, like text selection for copy/past or precision cursor adjustment. A user may make an initial selection on the front of the screen with a finger tap, then slide another finger on the back panel (or the sides) to adjust the final selection. The back touch may allow the user to move the cursor in a fine-grained manner without the front finger obstructing the user's view. Alternatively, a touch on the touchscreen may initially place the cursor, then use of the back panel may act like a mouse pad function that supports smaller scale cursor movements. In various embodiments, a smaller scrollable space on the back of the device to correspond to a larger region of movement on the front (i.e., scaled movement). Such scaled movement may improve one-handed reach of features on the mobile computing device.

FIGS. 29A and 29B illustrates a user performing another combination of gestures, one on the back panel and another on the touchscreen of the mobile computing device to perform certain functions. For example, a strong tap on the back panel may be used to copy selected text, then a strong tap on the front of the screen may paste the copied text. Alternatively, two-handed text entry gestures may include swipe down on the sides to switch text entry keyboards; tap both thumbs on the side of the phone to toggle between an emojis list and a keypad/keyboard; or tap both thumbs along the side, and the height of the tap will determine the emoji keypad that is brought to the foreground.

FIGS. 30A and 30B illustrates a user performing another combination of gestures, one on the back panel and another on the touchscreen of the mobile computing device to perform certain functions. For example, a strong tap on the back panel of the mobile computing device may bring the previously opened application to the foreground. Optionally, the previous application may be visually shown to move forward on the home screen, in an animation, like the task switcher. Then a strong tap on the front may send the current application to the back ground.

FIGS. 31A-32B illustrate some examples of a user's grip being detectable to cause the mobile computing device (e.g., mobile computing device 100 in FIGS. 1A and 1B) to perform a predetermined function, in accordance with various embodiments. Various embodiments detect normal grip holding patterns (when the user is just holding the device) from intentional touch and gestures on the back or side. Specific aspects and variations of various embodiments include:

-   -   Detecting a unique grip to trigger the detection mode for         back/side touches. For example, user may place the middle and         index finger close together, which is not the normal way for         holding the device.     -   Detecting a unique tap or back/side gesture to listen for other         back/side gestures. In other words, the device may only (always)         be watching for a hard back tap (which is not normally         associated with a standard holding grip). Once this is         identified, then it can start listening for other kinds of         back/side touches.     -   Utilizing contextual cues to trigger the detection mode for         back/side touches. For example, the currently displayed app         could provide the trigger. Likewise, the device position could         provide the trigger (lying flat on a table could allow back/side         touches) or utilize environmental characteristics to trigger the         detection mode for back/side touches. For example, if the         ambient brightness is very high and different from when the         display brightness was last set, then allow a back touch to         adjust brightness level.     -   Detecting combinations of grip and context may trigger         functions.     -   Grip and/or context may also enable different sets of back/side         touches to be performed.     -   Shaking the phone is another way to trigger a mode that allows         the user to use back/side touches.

In some embodiments, a particular grip (e.g., one-handed grip), once detected, may change a threshold needed for certain gestures or particular touch inputs through the touch sensors to be recognized or to trigger other functions. This type of feature may allow the user to be less accurate in their inputs of certain touch patterns or gestures. For example, a classifier used by the processor to match received input patterns to stored patterns of recognizable gestures may require a less perfect match while the mobile computing device is being gripped in the one-handed mode as compared to other modes. In addition, this feature may limit accidental false triggering of special actions (such as one-handed mode) by constraining their activation to certain grips or circumstances with which users interact with their mobile communication device.

FIGS. 31A and 31B illustrates a user gripping a mobile computing device, which automatically activates certain features. The user's grip method may be detected by the touch sensors. Thus, such contextual awareness data may be used to provide an offset between a target location on the touchscreen and the actual location that gets touched. A processor may detect the type of grip and adjust the expected offsets accordingly for improving touchpad accuracy and performance. One-handed right-hand, one-handed left-hand, and two-handed grips may be accommodated in this way.

FIGS. 32A and 32B illustrates a user gripping a mobile computing device, which automatically activates certain features. A processor of the mobile computing device may categorize a detected grip and then optimize the user interface for the detected grip. For example, the user interface may automatically toggle between a one-handed mode (i.e., FIG. 32A) and a two-handed mode (i.e., FIG. 32B), when the user changes grip. In addition, the user interface may automatically show the one-handed user interface shifted to one side; the side toward the gripping palm. Also, the processor of the mobile computing device may detect the size of the hand and vertical location along the display, to optimize the one-handed user interface. This may allow a user to scroll up with back-touch, and access content that is out reach from the front facing finger/thumb.

Various embodiments may be implemented one or more of a variety of mobile computing devices, an example of which in the form of a smartphone is illustrated in FIGS. 33A and 33B. With reference to FIGS. 1A-33B, a mobile computing device 100 may include a body 110, constructed of a plastic, metal, ceramic, glass, or a combination of such materials, for containing all or some of various components.
